The PUF60, a protein related to RNA splicing, plays critical functions in RNA splicing and gene transcription regulation. In addition, it can achieve synergistic binding with U2AF65 on RNA through interactions in the pyrimidine region, promoting the splicing of introns with weak 3'- splice sites and pyrimidine bundles. Nevertheless, an increasing amount of evidence supports that it shows a significant overexpression pattern in the vast majority of cancer cells and is crucial for embryonic development, indicating that PUF60 may hold the post of a potential therapeutic target for such diseases. These studies have significantly increased our interest in PUF60. Thus, we briefly reviewed the structural domain characteristics of the PUF60, splicing mutants of PUF60, and the roles and functions in human diseases, including various cancers, infections of bacterium and viruses, myositis, and Verheij syndrome.

This study aims to elucidate the apoptotic mechanism of CEG against the melanoma cancer cell line (A375).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The study estimated the IC50 of CEG against the A375 cell line and assessed cell viability, apoptosis, and necrosis upon CEG treatment. Additionally, IC50 values of CEG against Phosphoglycerate kinase1 (PGK1) and Pyruvate Kinase M2 (PKM2) were determined at various levels of concentrations. The impact of CEG on intracellular glutathione (GSH) levels and the activity of key enzymes (GR, SOD, GPx, CAT), as well as markers of apoptosis (P53), and cell cycle regulation (cyclin D1, cyclin E2, cdk2, cdk4), were estimated. Finally, the level of AMP-activated protein kinase (AMPK), PGK1, and PKM2 gene expression levels in A375 cells were also evaluated.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The IC50 value of CEG against A375 cells was determined to be 41.87 ± 2.47 µg/mL. A375 cells treated with CEG showed a significant increase in the G0/G1 phase and a decrease in the S and G2/M phases, indicating cell cycle arrest and reduced proliferation. Additionally, there was an increase in the sub-G1 peak, suggesting enhanced apoptosis. Additionally, the pharmacological analysis revealed potent inhibitory activity of CEG against both PGK1 and PKM2 gene expression, with IC50 values 27.89, 11.70, 7.43 and 2.74 µg/mL after incubation periods intervals of 30, 60, 90 and 120 minutes, respectively. In In-Silico study, computational simulations showed a strong binding affinity of CEG towards AMPK, PGK1, and PKM2 activities, with estimated binding energy (∆G) values of -6.5, -7.9, and -8.3 kcal/mol, respectively. Furthermore, incubation of A375 cells with CEG (at concentrations of 20.9, 41.87, and 83.74 µg/mL) led to a significant decrease in GSH levels and the activity of GR, SOD, GPx, CAT, cyclin D1, cyclin E2, cdk2, and cdk4.
